Hola a todos<br>
<br>
Alguien se ha visto en la necesidad de hacer resolución inversa con
IPs asignadas por LACNIC del segmento 170.80.0.0/16?, al parecer en
un principio estaba asignado a ARIN pero fue cedido a LACNIC, el
tema es que a la hora de querer resolver inversamente, la solicitud
se queda en servidores de ARIN, ya lo reporte con ellos pero me
mandan a LACNIC, pero según yo falta que ARIN delegue el segmento
170.80.0.0/16 a Servers de LACNIC. (Ya revise mis DNS Servers y si
resuelven autoritariamente por el segmento asignado en cuestión).<br>

Prueba de DNS Query hacia IP ejemplo 170.80.28.1<br>

<i>Step 1</i><i><br>
</i><i>We are at the first step. All DNS queries, if not previously
cached (and we do NOT cache), starts from the root servers.</i><i><br>
